Nurse competence in aging overview.

This article provides an overview of the Nurse Competence in Aging (NCA) project. Specifically, it reviews demographics, articulates the need to increase the gerontology presence within specialty nursing, and analyzes the way in which NCA is addressing that need in partnership with specialty associations.

Two independent promoters as well as 5' untranslated regions regulate Dd ras expression in Dictyostelium.

The Dd ras gene produces three transcripts during Dictyostelium development. The largest transcript (L-) can be induced by external addition of cAMP even in cells prevented from aggregating, whereas shorter transcripts (S1- and S2-) expression requires cell aggregate formation. We show the presence of two independent promoters for L- and S-transcripts by deletion analysis of Dd ras fragments fused to CAT reporter genes reintroduced in Dictyostelium.

Isolation of two genes encoding putative protein kinases regulated during Dictyostelium discoideum development.

Two Dictyostelium discoideum protein kinase(PK)-encoding cDNAs (Dd PK1 and Dd PK2) have been isolated by hybridization with an oligodeoxyribonucleotide derived from a highly conserved region of eukaryotic PKs. The two nucleotide (nt) sequences encode new putative serine/threonine-specific PKs. Dd PK1 is a partial cDNA covering the entire catalytic domain.
